To all whom t may concer/n.:

Be it known that l, HERMAN J. SoHUUrz, a citizen of the United States, residing in the city of Chicago, county of Cook, and State of illinois, have invented certain new and useful Improvements in Inserting Machines, of which the following is a specification.

This invent-ion relates to improvements in inserting machines and relates more particularly to a machine to be used in connect-ion with a binding machine whereby insert material is placed upon the open binders or books or pamphlets which are travelling in the bindin machine feed.

Among t e salient objects of the invention are to provide an insert machine automatically controlled by the binding machine feed so that the inserts are'fed and deposited upon the open binders as they pass in the binding machine and so controlled that where there is a blank space in the binding machine, the feed of the insert machine is automatically interrupted; to provide an insert machine in which the inserts are selected from a magazine singly and fed to automatic feeding rolls and bands and accurately positioned upon the binders which are subsequently closed as the binders pass along in their travel in the binding machine; to provide a machine in which large or small inserts may be accurately and uniformly fed to be deposited properly in the binders; to provide a machine which 1s simple in operation and automatic in every detaii.

fn the drawings:

Fi 6 shows the interior of the pull roll whic is inserted in the broken-away section shown in Fig. 5.

Fig. 7 `is an enlarged detail view of the feeding mechanism. l

For simplicity in the specification, the side of the machine which is set next to the semi no?. asasea binding machine will be considered as the front, and the opposite side as the rear, the driving side of the machine as the left side and theopposite side the right. The machine adaptable to insert envelopes, papers or any desired insert material into the open binders of pamphlets, books, catalogs or other bound material passing along in the binding machine feed is mounted on the side of the binding machine by means of a support 1. The open binders 2 passing throu h the binding machine are carried alonen by the traveling feed of the binding maghine shown diagrammatieally at 3 and 3a. The details of the binding machine are omitted from the specification as they are no part of this invention. 'It is sulicient to say that the binder leaves of the bound material pass beneath the plate 4 and the feed bands 5 of the inserting machine. The inserting machine itself comprises a magazine 6, which is sapn ported upon the shaft 7 and adjustably regulated by means of the thumb screws 8. The angle of the magazine*which controls the feed of the insert material is adjusted by means of the screw 9 in the slot 10. rlhe in serts which may lcomprise envelopes or papers as shown at 11 are stacked in the' magazine, and are Weighted as shown so that they feed properly by a rod 12 pivoted to the frame 13 of the inserting machine by a shaft 14. The inserts are selected singly from the magazine by means of pull rolls 15. mounted on the shaft 16. Ill`hese rolls pass the inserts to upper and lower feed rolls 17 and 18 mounted on shafts 19 and 20 respectively. The feed rolls draw the inserts into a position to be fed between the upper feed bands 5 and lowerfeed bands 21. The up' per feed bands ride over pulleys 22 on shaft 23 and pulleys 24 on shaft 25. The lower feed bands 21 run over pulleys 26 on shaft 27 and pulleys 28 on shaft 29. The bands are placed a slight distance apart so that the insert feed will be unobstructed and there will be no crumpling of the paper in the upper and lower bands. These feed bands may beof any desired material such as fabric or rubber, the fabric being more desirable as it permits of smoother operation. The shafts carrying the pulleys for the feed bands are mounted upon secondary frames 30 extending out over the binding machine feed, the binder covers 2 passing beneath the frames andinto position so that the inserts travelling down between the bands will be deposited accurately upon the open binder covers. The power for the machine is transferred from a shaft beneath the binder machine u on which is mounted a sprocket over whic rides a chain 31driving the sprocket 32 on the shaft 33. A gear 34 is also mounted upon the shaft and drives the gears 35 and 36 which in turn drives the gear 37.mounted on the shaft 38. VThis gear,

through an intermediate gear 39 drives the shaft through the gear 40. Upon the shaft 20 is mounted Va second gear 41 which -meshes with a gear 42 mounted directly bands.

Describing now the feed interrupting device which is operable from thebound material which passes along in the binding machine feed, the plate 4 which is positioned horizontally above the open leaves 2 is slotted as shown at 47 and in this slot is -positioned a flexible finger 48, which is pivoted on the shaft 49 supported by bearings 50. and connected by means of a link 51 to the weighted connection 52 mounted on a shaft 53 carried by bearings 54 mounted on the frame 13. As the open leaves pass along in the binding machine feed, the finger 48 contacts the leaves holding the finger in substantially horizontal position. Where there is an interruption in the binding machine feed, that is, where there is a blank space or a binder omitted, the finger 48 will drop down, rotating the shaft49 and causing the weight 52 to rotate the shaft 53 in a clockwise manner. lThis rotates the upstanding projection or shoe 54a mounted on the shaft 53 into a position where the roller 55 mounted on a pawl 56 passes over the bevelled end of the shoe and raises the pawl from engage.- ment with the notch in the disk 57. The functioning of the pull rolls is accomplished by the action of the pawl 56 which is mounted on a disk 58. This disk 58 is fixedly connected to a gear 59 which meshes with the gear' 37. Disk 58 is rotatably mounted on the shaft 16, upon which is also mounted the pull rolls 15. The disk 57 is fixedly mounted to the shaft 16 and when the shoe 54a is ro-- tated away from a position before the roller 55, the pawl 56 will remain in engagement with the notch in the disk 57 and cause the shaft 16 to rotate, being driven through the gears 37 and 59. When, however, the nger isidro? 48 fails to contact with the binder leaf in the binder machine, the shoe 54x71 will be rotated into position so that the roller will disengage the pa-wl from the notch in the disk 57 and due to the braking action imposed by a brake band 60 acting on the opposite end of the shaft 16, the rotation of the shaft will be stopped and the continuous feed of the inserting material interrupted. The positioningv of the plate 4 and the linger 48 and the timing of the mechanism is such that the functionmg of the finger 48 will operate to interrupt the depositing of the inserts in the blank spaces as they register beneathy the feed bands in their travel.

The pull rolls 15 mounted on the shaft 16 comprise a shell portion 15a which is cut away as shown at 15" and adapted to accommodate the bridge block 61 which has a central bearing for mounting the same upon the shaft 16. About the outer periphery of the bridge block is fitted an elastic band 62, a portion of which conforms with the outer surface of the pull roll. The bridge block is slotted as shown at 63 and the elastic band instead of covering the entire bridge block as shown in Figs. 3 and 7, may be threaded through one of the slotted holders and thereby made to cover only a portion of the exposed outer surfaces of the bridge block. The purpose of shortening and lengthening the exposed elastic band is to regulate the pullingefect of the pull roll, that is, where a narrow insert such as an envelope is to be made, it is only necessary to have a short surface of the pull roll contact with an envelope to properly feed it to the feed rolls while in longer inserting material such as a sheet of pa er or the like to be fed, the duration o pulling contact must be of greater length so that the sheet will be uniformly fed between the pull rolls and the. lower bed roll 64. These lower bed rolls are in a position directly below the pull rolls and are stationary during the operation of'- the machine. They are mounted upon a lower shaft 65 by means of eccentric bearings 66. These eccentric bearings are maehined as shown at 67 to be fitted by a spanner'wrench whereby the rolls may be positioned at any desired distance from` the up per pull roll. The eccentric bearings being positioned at both ends of the shaft 65 where the same is supported in the frame 13 furnishes ay means for accurately positioning the lowerbed rolls so that only a single A insert can be fed between the pull rolls and lower bed rolls.

Tn the drawings, the lower bed roll is shown with an outer surfacing of rubber at 68 but this material is unnecessary as a wood or steel roll would serve as well. The upper feed rolls 17 are of rubber and the lower feed rolls 18 are of steel. Here again, the proper feed may be obtained by the use of different compositions but the contact between the rubber and steel serves to satisfactorily advance the sheets so that they are fed properly between the feeding tapes.

The tapes travel over crowned pulleys and deposit the inserts accurately upon the open binder leaf due to the careful timin of the apparatus with the feed of the binding machine. The machinestake up little space and due to their automatic operation require very y little attention.
